Get values from JSON string - Objective C

Question

I have this JSON response string:

{"d":"{\"ID_usuario\":\"000130\",\"Nombre\":null,\"Vipxlo\":0,\"Provmun\":null,\"Descuentos\":null,\"Listaviplocal\":null}"}`

With this code:

- (void)connectionDidFinishLoading:(NSURLConnection *)connection 
{
    //Check valid signal

    connection = nil;

    NSString *responseString = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding];
    //data =nil;

    NSArray *jsonArray = [responseString JSONValue];

How can I do it?

When you can afford to require iOS 5 you should try NSJSONSerialization.

Your code could look like this but I suggest reading the Docs first.

    NSArray* jsonArray = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableLeaves error:someError]
